Usage Guidelines

On the device, service modules generate logs and control the log volume. The information center processes the received logs.

When the number of logs that are generated within a specified period (T) exceeds the threshold, the service module, with the buffer mechanism, saves extra logs to the buffer and does not send them to the information center.

You can run the display buffer command to view statistics about log information in the buffer.

Example

# Display statistics about logs cached in the buffer on the service module L2IF.
